Paul, I think what AngelThMan is saying is that, science will never, ever create life synthetic or otherwise, completely from scratch. As in, with no tools or equipment of any kind whatsoever. Essentially, it is impossible for a human being to just create life with nothing but his bare hands and his mind.* Doing this might be rather interesting and, if it were done, would still prove nothing about God except that it is in fact possible to create life from scratch in the first place. It lends more to God than against Him.
